PUMP FORQCOMBUSTION-ENGINES.

SPECIFICATION forming part of Letters Patent N 0. 722,008, dated March3, 1903. Application filed November 21,1901. Serial No. 83,132. (Nomodel.)

To aZZ whont it may concern:

Be it known that I, GEORGE A. GEMMER, of Marion, county of Grant, andState of Indiana, have invented a certain new and useful Pump forCombustion-Engines and I do hereby de clare that the following is afull, clear, and

exact description thereof,reference being had to the accompanyingdrawings, in which like numerals refer to like parts.

The object of this invention is to improve the connection betweenthecarriage or other movable part of a combustion-engine and the plunger ofthe fuel-pump used with such engine, so that said plunger can be readilydisengaged from the moving carriage and be operated by hand, if desired,and then readily connected with the carriage.

In the drawings, Figure 1 is a side eleva tion of a pump and a portionof the carriage or movable part of a combustion engine.

Fig. 2 is a section on the line A A of Fig. 1

with the plunger shown in dotted lines'disengaged from the carriage.Fig. 3 is an end elevation of the handle connected'with the plunger ofthe pump. Fig. 4 is a side elevation of the handle and plunger. Fig. 5is a side elevation of an engine With my invention thereon, parts of theengine being broken away.

The combustion-engine with which this apparatus is adapted to beconnected is not here shown, as the construction of such engine isimmaterial, provided there be a horizontallyreciprocable means orcarriage 1, that is actuated by the engine, either from the shaft orotherwise, whereby the pump may be mechanically driven.

2 is a cylinder of a gasolene-pump whereby gasolene is drawn from a tankor other source of supply (not here shown) and forced to the vaporizer.(Not here shown.)

The specific construction of the gasolenepump is immaterial to thisinvention, and the connections between it and the tank and the vaporizerare likewise immaterial.

The pump has a plunger 3, that has secured to its outer end a handle 4,with a projection 5, extending at a right angle from the plunger. A pin6 extends centrally from the outer end of the plunger and in linetherewith. An arm extends downward from the moving carriage 1 of theengine that has two lugs 7 and S, the lug 7 extending down in the pathof the plunger 3 and having in its lower end a hole (shown in dottedlines of Fig. 1) to receive the pin 6 of the plunger and hold it inalinement. A recess 9 is'made between the lugs 7 and 8 to receive theprojection 5 from the plunger, whereby said projection'5 fits betweenthe two lugs 7 and 8 from the carriage and remains in said positionwhile the handle at is in a vertical position, as shown in Figs. 1 and2. Then the plunger is drawn back and forth with the movement of thecarriage 1. When the handle is turned to a horizontal position, as shownin dotted lines in Fig. 2, the projection 5 from the plunger disengagesthe lugs 7 and 8 on the carriage, and then the plunger may be operatedby hand independently of the carriage.

It is often necessary to actuate the fuelpump by hand, and this is avery simple and convenient mechanism to enable the plunger to bedisconnected and actuated by hand. After it hasbeen actuated by hand itis connected with the carriage by inserting the pin 6 into the hole inthe lug 7 while the handle is in a horizontal position and then turningthe handle to the vertical position. weight of the handle will maintainthe connection during the operation of the machine.

The moving means or carriage 1 referred to is shown in Fig. 5 asreciprocable on the guide-rod 10 and is actuated by theconnecting-rod11, crank-gear 12, pinion 13, and main driving-shaft 14.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. In a combustion-engine, a movable part of the engine, a fuel-pumphaving a plunger beside and extending parallel with the direction ofmovement of said movable part of the engine, and means on the plunger toengage or disengage it with said moving part of the engine by turningthe plunger on its axis.

2. In a combustion-engine, a horizontallyreciprocating member, afuel-pump having a plunger mounted horizontally parallel with the lineof movement of said reciprocating member, and means for engaginganddisengaging the plunger with said reciprocating member by turning theplunger on its axis.

3. In a combustion-engine, a reciprocating member having one or moreprojecting lugs,
